Which platform is pictured in the International Space Station photo (re-posted below)? It is clearly a spar (basically a large vertically floating cylinder), and like most GoM spars appears to be the truss type (see diagram below depicting spar types). There are currently 18 GoM spars (list in table below). Looking at photos of these spars, my guess is that the SpaceX Dragon is pictured above Perdido (bottom photo).

This is Devils Tower Spar with the spacex crew capsule during re-entry. When the picture was taken, the platform was in the middle of a drilling campaign and one of the support vessel captains positioned himself to take this picture. I supported Devils Tower during this time and loved using this picture during presentations.
Thank you!
